There are several tasks that are pending to be done, I have classified them
by dificulty levels:

= Relatively easy =
 [ ] improve shell scripts for keepalived/heartbeat: *really* important
 [ ] NACK as default protocol
 [ ] rename persistent to alarm
 [X] manpage for conntrackd(8)
 [ ] add scripts to use the floating priority feature in keepalived to avoid 
     premature take over.
 [ ] ignorepool with unlimited size and ignore networks
 [ ] selective conntracks removal
 [ ] debian/rpm packages
 [ ] improve website
 [ ] Dumazet improvement hashtable (multiply vs. divide)
 [X] add secmark support

= Requires some work =
 [ ] study better keepalived transitions
 [ ] test/fix ipv6 support
 [ ] add support setup related conntracks
 [ ] NAT sequence adjustment support

= Open issues that won't be ever resolved =
 * unsupported stateful iptables matches:
   * connbytes: probably the persistent may support it
   * recent: requires further study
   * quota: private data counters

= conntrack =
 * add support for -D --dport 1000
 * improve error messages
 * add support for SCTP (requires kernel >= 2.6.25)
